VECTORED INTERRUPT CONTROL SYSTEM REINFORCED BY CO-WORK OF HARDWARE AND SOFTWARE THROUGH DIRECT TRANSFER OF INTERRUPT INSTRUCTION VECTOR, AND METHOD THEREOF

摘要

PURPOSE: A vectored interrupt control system reinforced by co-work of hardware and software through direct transfer of an interrupt instruction vector, and a method thereof are provided to enable a CPU to perform a service routine of a corresponding address by regenerating the interrupt instruction vector and directly transferring it to a wrapper, when offset information is generated in an interrupt controller. CONSTITUTION: The interrupt controller(110) receives an interrupt generating signal from each interrupt sources, and outputs interrupt request information and the offset information by responding to the interrupt generating requests corresponding to the top priority. The CPU(120) generates/outputs an interrupt address and a program address, and performs the service routine by receiving service data. An interrupt information regenerator(130) generates/outputs an interrupt service address vector by receiving/reprocessing the interrupt address and the offset information. An interrupt selector(140) generates a multiplexer control signal having the first and the second logical state. The wrapper(160) outputs a memory pointing address matched with the address output from a multiplexer(150) depending on an OS(Operating System).
